Die cast metal enclosure with BEST cylinder (construction core included)
OPEN/CLOSE spring return to center (OFF) key removable in center position only. Should only be used on operators wired for constant pressure to open and close (all LiftMaster industrial operators with type D control wiring).
May be used in two different ways: as an OPEN only control (all LiftMaster operators) or as an OPEN/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring).
In the latter case pulling the cord will open a fully closed door close a fully opened door and reverse a closing door.
Pulling the cord whlie the door is opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).

OPEN/CLOSE spring return to center (OFF) key removable in center position only. Should only be used on operators wired for constant pressure to open and close (all LiftMaster industrial operators with type D control wiring).
The MWT12 safety edge transmitter is designed to provide wireless signal transmission form the safety edge to the motor controls.
It is easily mounted and wired to the gate or door edge sensor. When the sensing edge comes into contact with an obstruction a closed circuit signal is created and is sent to the transmitter.
The transmitter relays the information to the receiver and the receiver passes the signal along to the operator motor.
The gate or door stops movement and will then reverse the direction of travel.
Comes standard with a NEMA 4 weather-proof enclosure. The enclosure can be easily mounted with the four mounting holes and screws provided
